Manufacturer needs to implement it after approaching carrier.VoWiFi not working with my Cell C sim in OnePlus6.
Hi MinoscI have been with CellC for many years and had a number of issues in the past. However in the last couple of months I have experienced a vast improvement in their services, (network, value for money and satisfactory responses to queries)
I must however admit that I don't feel comfortable with the service at their branches and do most of my communication via telephone or the net.
Keep up the good work.
